One way to get more in touch with your experiencing self is to practice <a href=\"https:\/\/www.shortform.com\/app\/book\/the-master-guides-choosing-a-meditation-practice\/1-page-summary#styles-of-buddhist-meditation\" rel=\"nofollow\">mindfulness meditation<\/a>, which trains you to accept each moment-to-moment experience as it happens, then let it fade away naturally\u2014you don\u2019t judge the experiences as \u201cgood\u201d or \u201cbad,\u201d and therefore you don\u2019t try to consciously remember the good experiences or block out the bad ones.)&nbsp;<\/p>\n\n\n\n<p>In contrast, the remembering self reflects on past events, and only evaluates them once they\u2019ve passed. As a result, it measures happiness very differently from the experiencing self. Kahneman identifies two key patterns that the remembering self uses to evaluate past events:<\/p>\n\n\n\n<p><strong>1. The <a href=\"https:\/\/www.shortform.com\/blog\/peak-end-rule\/\">peak-end rule<\/a>:<\/strong> This measurement depends mainly on an event\u2019s peak intensity (positive or negative) and how it ends, not an overall average of how it felt. For example, a musical with one excellent song and a strong ending is likely to earn good reviews, even if the majority of the show is mediocre.<\/p>\n\n\n\n<p>(Shortform note: <a href=\"https:\/\/www.shortform.com\/blog\/the-peak-end-rule\/\">The peak-end rule<\/a> has significant implications for <a href=\"https:\/\/www.psychologytoday.com\/us\/blog\/social-instincts\/202510\/3-ways-to-beat-the-peak-end-rule-in-your-relationship\" target=\"_blank\" rel=\"noreferrer noopener\">how we think about our relationships<\/a>. We tend to view relationships\u2014whether current or past\u2014through the lens of a few key moments, and evaluate the entire relationship as positive or negative based only on those moments. However, you can intentionally create more of those moments to help you remember the entire relationship more accurately. One effective way to do this is simply by diversifying the experiences you and your partner share together. For instance, instead of going to the same bar or restaurant every time you go out, make a point of trying out places you\u2019ve never been to; each of those new experiences will have its own peak and end moments to remember.)&nbsp;<\/p>\n\n\n\n<p><strong>2. <a href=\"https:\/\/www.shortform.com\/blog\/duration-neglect\/\">Duration neglect<\/a>: <\/strong>How long something lasts has little impact on how we remember it. For instance, two people with similarly painful injuries (say, ankle sprains of equal intensity) will feel roughly the same about those injuries after the fact, even if one person only needed a month to heal while the other took six months to get back to full health.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Counterpoint: Duration Has an Indirect, but Significant Impact<\/strong>As a counterpoint to Kahneman, a study from 2020 found that the duration of an experience <em>does<\/em> have a significant impact on how we remember it, <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0010027721001694\" target=\"_blank\" rel=\"noreferrer noopener\">but the effect is indirect<\/a>. While the researchers agree that people only remember key moments about an experience, how long the experience lasts changes <em>how <\/em>they remember those moments.&nbsp;<br><br>Applying this study to the previous example, two people with painful injuries will have similar memories about their experiences: They\u2019ll remember only a few key moments, regardless of how long they were injured and in pain for. <strong>However, they\u2019d remember those key moments differently. <\/strong>For instance, the person who took six months to heal might remember their most painful moments as significantly worse, because when recalling them, they felt fatigued and frustrated (due to their lengthy healing process). The person who only took one month to heal might remember those painful moments as being less severe, as they were better able to cope with those moments. Conversely, the person who took longer to heal might remember those moments <em>less <\/em>intensely because they\u2019d gotten so accustomed to the pain already.&nbsp;<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-remembering-self-skews-our-judgement\"><strong>The Remembering Self Skews Our Judgement<\/strong><\/h2>\n\n\n\n<p>Kahneman says that, because of its reliance on <a href=\"https:\/\/www.shortform.com\/blog\/system-1-thinking-kahneman\/\">System 1 thinking<\/a>, the remembering self distorts how we measure our own happiness, leading us to believe our lives are better or worse than they really are. Furthermore, because we make decisions by using our memories as reference points, <strong>we tend to heavily weigh decisions toward the remembering self and overlook the needs of the experiencing self.<\/strong>&nbsp;<\/p>\n\n\n\n<p>Some key flaws in the remembering self\u2019s reasoning include:<\/p>\n\n\n\n<p><strong>Needless suffering:<\/strong> People often make choices that cause the experiencing self to suffer, but end with rewards that the remembering self will enjoy (due to the <em>peak-end rule<\/em>). For example, boxers regularly suffer through harsh training and brutal fights just for the chance of a memorable victory. While this may seem reasonable if good memories will strongly outweigh bad ones, Kahneman argues that the experiencing self\u2019s pain still negatively impacts your overall happiness, and it\u2019s better to avoid such suffering whenever possible.<\/p>\n\n\n\n<p>(Shortform note: Objectively speaking, your past experiences can definitely impact your current happiness and well-being\u2014consider how a sprained ankle affects your happiness <a href=\"https:\/\/www.txfoot.com\/post\/could-i-have-an-ankle-sprain-without-knowing-it\" target=\"_blank\" rel=\"noreferrer noopener\">regardless of whether you know how you hurt it<\/a>. To further illustrate Kahneman\u2019s point, research shows that people who experienced childhood trauma can suffer from ongoing physical and mental PTSD symptoms, <a href=\"https:\/\/www.kvc.org\/blog\/children-may-not-remember-trauma-but-their-bodies-do\/\" target=\"_blank\" rel=\"noreferrer noopener\">even if they don\u2019t remember the traumatic experiences<\/a>. Similarly, you might have aches and pains from old injuries you don\u2019t remember getting, or certain situations might put you on edge for reasons you can\u2019t explain.)&nbsp;&nbsp;<\/p>\n\n\n\n<p><strong>The <a href=\"https:\/\/www.shortform.com\/blog\/focusing-illusion\/\">Focusing Illusion<\/a>:<\/strong> When trying to evaluate their overall happiness, people place too much emphasis on whatever\u2019s currently on their mind\u2014in other words, whatever the remembering self is thinking about at the moment. For example, suppose a couple is going through a rough patch; they might evaluate their entire marriage as a net negative because they\u2019re only remembering the problems they\u2019ve recently had, even though both partners are generally happy with each other. On the other hand, if someone specifically asks how good their marriage is <em>when they\u2019re not fighting<\/em>, that would shift their focus and probably change their answer.<\/p>\n\n\n\n<p>(Shortform note: One possible way to mitigate the focusing illusion is to consider the same issue while you\u2019re in various different moods or frames of mind. Apocryphally, ancient Persians used to deliberate over <a href=\"https:\/\/www.shortform.com\/blog\/important-decisions-in-life\/\">important decisions<\/a> twice: <a href=\"https:\/\/www.forbes.com\/sites\/chunkamui\/2016\/03\/22\/wine-and-sleep-make-for-better-decisions\/\" target=\"_blank\" rel=\"noreferrer noopener\">once while drunk and once while sober<\/a>. They did this to shift their focus and consider different aspects of a situation. Supposedly, only a decision that seemed wise in both states (drunk and sober) was acceptable. While it may not be advisable to get drunk every time you have to evaluate a situation, there <em>is <\/em>value in reconsidering a decision later, especially one made in an emotional moment\u2014you may find that you make a different choice once your feelings have settled and your focus has shifted.)<\/p>\n\n\n\n<p><strong>Inaccurate Predictions:<\/strong> Kahneman says that people consistently overestimate how much changes will affect their future happiness (positively or negatively) because their current remembering self overestimates how much their future experiencing self will think about those changes. In reality, people quickly adapt to new circumstances and stop thinking about them at all. For example, people commonly think they\u2019d be happier if they had more money. However, once they achieve their <a href=\"https:\/\/www.shortform.com\/blog\/goals-change\/\">financial goals<\/a>, that level of wealth becomes their new normal and their happiness settles to the same level it was at previously, at their old normal.&nbsp;<\/p>\n\n\n\n<p>(Shortform note: These inaccurate predictions about the future lead to a phenomenon that psychologists call the <a href=\"https:\/\/thedecisionlab.com\/reference-guide\/psychology\/hedonic-treadmill\" target=\"_blank\" rel=\"noreferrer noopener\"><em>hedonic treadmill<\/em><\/a>: People chase after something they think will make them happy, enjoy a moment of pleasure when they get it, but quickly return to their previous level of happiness. They then start chasing the next thing in order to recapture that feeling. It\u2019s referred to as a treadmill because people constantly \u201crun\u201d after happiness, but always end up in the same place emotionally. The same is true of negative experiences\u2014after a brief period of feeling upset or angry, people go back to feeling how they did before.)&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-conclusion-both-selves-are-important\"><strong>Conclusion: Both Selves Are Important<\/strong><\/h2>\n\n\n\n<p>Kahneman urges you to find a balance between these two selves, because focusing too much on one or the other creates problems.<\/p>\n\n\n\n<p><strong>Focusing only on the remembering self invites unnecessary suffering.<\/strong> If you only value the remembering self, you might endure decades of pain in the hopes of a brief period of happiness at the end. Conversely, you might avoid long periods of happiness because you\u2019re afraid they\u2019ll end poorly.&nbsp;<\/p>\n\n\n\n<p>For example, you may choose a career you don\u2019t enjoy simply because it pays well. You would then devote the majority of your life to something that makes you unhappy because you think it will allow you to enjoy the relatively brief period between your retirement and your death.&nbsp;<\/p>\n\n\n\n<p>On the other hand, Kahneman warns that <strong>focusing only on the experiencing self ignores the potential for lasting harm that some moments can bring. <\/strong>Therefore, this approach can lead to shortsighted decisions that maximize your immediate pleasure while harming <a href=\"https:\/\/www.shortform.com\/blog\/your-future-self\/\">your future self<\/a>.<\/p>\n\n\n\n<p>In short, both selves are important. To maximize your <a href=\"https:\/\/www.shortform.com\/blog\/happiness-and-wellness\/\">well-being and happiness<\/a>, Kahneman says <strong>you must consider the needs of both your experiencing self and your remembering self.<\/strong> This means you must weigh the moment-to-moment experiences of living against the long-term value you\u2019ll derive from your memories, and find a balance where you can be satisfied both in the present and in the future.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Be Content With the Present, Yet Excited for the Future<\/strong><br><br>Kahneman\u2019s advice to balance the needs of your two selves echoes what Daniel Z. Lieberman and Michael E. Long say in <a href=\"https:\/\/www.shortform.com\/app\/book\/the-molecule-of-more\/1-page-summary\" rel=\"nofollow\"><em>The Molecule of More<\/em><\/a>: Long-term happiness requires you to balance <a href=\"https:\/\/www.shortform.com\/app\/book\/the-molecule-of-more\/1-page-summary#happiness-requires-both-what-if-and-what-is-chemicals\" rel=\"nofollow\">excitement for future possibilities with contentment with your present circumstances<\/a>.&nbsp;<br><br>The authors explain that many people spend their lives pursuing \u201cmore\u201d\u2014more money, more possessions, more extreme experiences, and so on\u2014because getting what they want provides a pleasurable rush of <a href=\"https:\/\/my.clevelandclinic.org\/health\/articles\/22581-dopamine\" target=\"_blank\" rel=\"noreferrer noopener\">dopamine<\/a>. However, dopamine keeps you focused on future possibilities; you need to engage more present-focused areas of your brain to enjoy what you already have.<br><br>Lieberman and Long say the easiest way to find this balance is to look for a career or hobby that demands your full attention in the present, but also gives you future goals to work toward.
